From 1955, Raveel's work became more abstract. Partly influenced by some developments in painting on an international level, he wants to paint more spontaneously and freely. Motifs are reduced to shapes, planes, lines, sweeping lines, and are hardly recognisable any more. In About a human being, the figure has disappeared in some rudimentary forms. Even the identity of the face merges into a series of squares, something we also see in the preceding figurative work.
